X+2y=8 x-2y=-4 solve by system of equations
Vsevolod [243]

Answer:

Step-by-step explanation:

x + 2y = 8 -----------(I)

x - 2y  = -4 -----------(II)

Add equation (I) & (II) and thus y will be eliminated and we can get the value of 'x'

(I)           x + 2y = 8

(II)          <u>x - 2y  = -4</u><u>      </u>{Now add}

           2x         = 4

                   x   = 4/2

x = 2

Substitute x =  2 in equation (I)

2 + 2y = 8

    2y = 8 - 2

    2y = 6

      y = 6/2

y = 3
